llvm dev - Mar 2010 - [LLVMdev] Changed: Build errors for poolalloc using MinGW/gcc 4.4.0

Thanks Bob and John for the response. I am having problems building poolalloc
with my MinGW and gcc 4.4.0 setup. Running make in the poolalloc directory
results in a bunch of "undefined reference to ..." link errors
building Release/lib/LLVMDataStructure.dll. I looked at the command line for
this link and found that there are no libraries included with "-l..."
options even though there are a bunch of library path options with
"-L...". The first few errors are:

 

c:/llvm/llvm-2.6/poolalloc/lib/DSA/Release/Basic.o:Basic.cpp:(.text+0x96):
undefined reference to `llvm::PassInfo::registerPass()'
c:/llvm/llvm-2.6/poolalloc/lib/DSA/Release/Basic.o:Basic.cpp:(.text+0xde):
undefined reference to `llvm::TargetData::ID'
c:/llvm/llvm-2.6/poolalloc/lib/DSA/Release/Basic.o:Basic.cpp:(.text+0xe3):
undefined reference to `llvm::Pass::lookupPassInfo(int)'
c:/llvm/llvm-2.6/poolalloc/lib/DSA/Release/Basic.o:Basic.cpp:(.text+0x11a):
undefined reference to `llvm::Type::getInt8Ty(llvm::LLVMContext&)'
c:/llvm/llvm-2.6/poolalloc/lib/DSA/Release/Basic.o:Basic.cpp:(.text+0x12a):
undefined reference to `llvm::PointerType::get(llvm::Type const*, unsigned
int)'


After trying to understand Makefile.rules in the llvm directory I tried using
"make LOADABLE_MODULE=1" and this time the command line includes:

 

     -lffi -lpsapi -limagehlp -lm 


but I still get the undefined references. It looks like the correct
"-l..." option is not being generated. I'm guessing this is as you
(John) think a configure problem, but being currently a Windows developer I just
don't know enough about it to debug.

 

I am only interested in LLVM because of DSA which I learned about from the
Lattner et. al PLDI paper. It would be nice if I could get this to work. Any
help would be appreciated.

 

Thanks,

Yes.  I believe both static and dynamic libraries are
built.

That's good to know.
:)

Patrick, I assume you want to write some sort of LLVM pass that uses 
DSA.  To get this to work on Cygwin/MingW, what you want to do is to 
write a tool that statically links in DSA and your pass(es).  You can 
take the source code to the pa tool (poolalloc/tools/Pa) and modify it 
accordingly.

I think this method is preferable over Anton's suggestion of linking DSA 
directly into opt because it prevents you from having a modified version 
of the LLVM tools to maintain.
